  • Name: Continuously welded rail stress-free temperature detection

  The company cooperates with China Academy of Railway Sciences to develop and research NTS 3.X (stress-free temperature detection system). The continuously welded rail stress-free temperature can be obtained through three measured physical quantities of lifting force, displacement and rail temperature by adopting the principle that vertical force of the continuously welded rail corresponds to lifting stiffness without damage to the rail and without the initial parameters of the continuously welded rail. The detection provides accurate stress-free temperature variation parameters for the equipment management department, makes reasonable judgment for whether to dissipate and adjust the stress of the continuously welded rail and removes hazards of track buckling and broken rails.
